WILLIAM HARRISON AKENS, .OF LINESVILLE,r PENNSYLVANIA.

SPECIFIGATION forming part of Letters atent No. 629,284, dated July 18, 1,899.

Application iiled October 2 9, 1898. p

To @ZZ whom t may concern:

Be it known that I, WILLIAM HARRISON AKENS, a citizen of the United States, residing at Linesville, in the county of Crawford and State of Pennsylvania, have invented new and useful Improvements in Sash-Fasteners, of which the following is a specification.

My invention relates to improvements in sash-fasteners.

The object of the invention is vto provide a sash-fastener which will operate to hold the sash locked in any desired position, which cany be readily manipulated to permit thev sash to be raised or lowered by the finger and thumb of one hand of the operator, and'which when released will automatically relock the sash in the position to which it has been moved.

It is a further object ofthe invention to provide a device of this character which shall be simple in operation and inexpensive to manufacture.

The invention resides, essentially, in a window-frame having racks on each inner side, pinions carried by the window-sash and meshing with racks, and a rod carried by the window and having at its outer ends catches which by turning the rod in one direction or the other can be moved into or out of engage-v ment with the teeth of the pinions.

,The invention further resides incertain details of construction, which will more clearly hereinafter appear, and be specifically pointed out in the claims.

In the accompanying drawing, illustrating my invention, the gure shows the Windowlocked in a closed position and in dotted lines" the window partiallyraised and the catchesv out of engagement with the teeth of the pinions.

The numeral lindicates'the window-frame, and 2 the window-sash.

The numerals indicate rack-bars secured on the inner sides of the Window-frame, and the numerals-t indicate pinions journaled on the window-sash near opposite lower corners thereof and meshing, respectively, with the rack-bars.

The numeral 5 indicates a rod which is ro- Serial No. 694,941. (No model.)

tatably mounted on the lower rail of the sash and which in its central portion is suitably bent, as shown, to provi-de anger-hold 6 for turning the same and at its ends is bent outward at right angles to itself to form the catches '7 7, which are adapted to engage between the teeth of the pinions. A spring 8 tends normally to hold the parts in such engagement. The manner of securing the rod '5 on the sash is .preferably by providing the body of the ordinary thumb-catch 9 with a Y central recess,affording two arms 10, in which arms are formed curved portions, such as indicated by ll,which iit over the rod on either side of the nger-hold G. The nger-hold 6 is thus immediately beneath the hook of the thumb-catch 9, so that as the former is raised, as will be understood, to turn the rod 5 and move the catches 7 out of engagement with the teeth of the pinions said finger-hold will lie immediately beneath the hook of the thumb-catch, and the continued movement of the hand in the upward direction will operate to raise the sash. When the iinger-hold 6 is released, the spring S will operate to turn the rod in the reverse direction and bring the catches 7 into engagement with the teeth 'of the pinions, thereby preventing said pinions from turning and locking the sash in the required position.

Having thus fully described my invention, what I claim is- 1. A sash-fastener comprising a windowframe having rack-bars secured on its inner sides, a sash carrying pinions at its opposite sides meshing with said rack-bars, and a rod journaledl on said sash and having its central portion bent to form a iinger-hold and its outer ends bent to form catches to engage with the teeth of said pinions, substantially as described. l

2. A-sash-fa'stener comprising a windowframe having rack-bars secured on its kinner sides, asash carrying pinions at it-s opposite sides meshing' with said rack-bars, a thumb catch on said sash recessed in its centralportion to aord two arms, each of saidarms being provided on its side next lthe sash with an open recess aording a journal-bearing, a

rod mountedin saidjournal-bearingszmdhavmy hand in presence of two subsorbng Witing its central portion bent to form a ngernesses.

hold located beneath the hook of said thumb- Y T catch, and a catch at each end of said rod for l WILLIAM HARRISON AKEB S' 5 engaging the teeth of said pinions, substan- Vituesses:

tiztlly its described. THOS. LIMBER,

In testimony whereof I have hereunto set F. B. VAN LIEN.
